Abstract

A toy vehicle comprises a lift mechanism which allows the toy vehicle to be lifted from a support surface in a lifting motion and roll end over end over end. The lift mechanism includes a lift arm pivotally mounted to a housing of the toy vehicle. A lift arm actuating motor is coupled to a lift arm drive screw that is in threaded engagement with a lift arm drive nut. A strut is coupled between the drive nut and the lift arm. In operation, the lift arm actuating motor drives the lift arm drive screw and causes the lift arm drive nut to drive the strut and move the lift arm into an extended position, causing the lift arm to engage a support surface to lift the toy vehicle. In the extended position, the toy vehicle is sufficiently rounded to permit the vehicle to roll end over end over end.

11. A toy vehicle having a front end and a rear end and first and second lateral sides comprising:

a housing;

a plurality of road wheels located generally beneath the housing and including at least one road wheel rotatably mounted proximate the rear end of the toy vehicle so as to at least partially support the rear end and at least one road wheel rotatably mounted proximate the front end of the toy vehicle so as to at least partially support the front end;

a lift mechanism at least partially supported by the housing, the lift mechanism including;

a lift arm having first and second ends, the lift arm being pivotally mounted proximate the first end so as to pivot with respect to the housing between a retracted position so as to enable the toy vehicle to be supported on a surface by the plurality of road wheels and an extended position in contact with the surface supporting the toy vehicle so as to raise the plurality of road wheels from the surface;

a lift arm actuating motor;
